HEATING APIAR-ATUS FOR GAMING-MACHINES.

T0 all whom it may concern.' i

Be it known that I, HARRY IV. LoivE, a citizen of the United States, residing at Florence, in the county of Douglas' and State of Nebraska, have invented l'certain nev.' and useful Improvements inl Heating Apparatus for Canning-Machines, ofgwhich the following is a specification. i The object of the present invention is the provisionlof means whereby to quickly and uniformly heat fruits and similar materials in the process of canning and the invention is itc 11nd to be of particular advantage the steam cooking of tomatoes in the preparation of catsup. i i

In carrying out the invention I employl a system o f heating pipes Awithin a kettle, the

' extent throughout vas distinguished from the pipes being endless, preferably circular and having intercommunication between-the several pipes whereby the units are `similarly disposed relative to the source of" heat supply and thus equally heated to a uniform usual', heating ,coils having dead ends. The

Ypipes are";mor`e ')ver advantageously nested Within each other and disposed Ain vertical tiersvso that the heating effect is distributed Y ,vrgxloqre generally throughout the mass of vruaterialindergoing treatment thanx by heating systems heretofore in use.

In the accompanying drawing-:and in thefollowing detailed description" is set forth a preferredl embodiment of tice-invention.

As, howevijthe invention is capable of embodiment in othernnd varied lforms 4of construction it is to be understood that the drawing and description should be construed in anilustrative andlnot i'n an unnecessarily limiting sense.

In the drawings--Fignrel is a top plan view of the heating pipes, the kettle not being shown; and Fig. 2 is a vertical section on the line 2-2 of Fig. Having reference to the drawings in detail, the reference numerals 11 and 12 des- 4ignate respectively the upper and lower it's of a set of heating pipes provided f,on posite sides with intercommunicating p sages at 13 and 14. Each of the pipc units is preferably annular and steam is admitted thereto by way 0I' the passage 14 'from a supipes 11 and .12 are in' practice made sub- A stantially the same size and of a diameter Specification of Letters Patent.

and below the level of the materials therein.

Inside of the set of heating units -above described is disposed a second set preferably independent thereof and lcomposed of the three units 17, 18 and 19. The twounts 17 and 18 being of dissimilar size and arranged the latter within the former, both being in substantially the same horizontal plane as the unit 12 of the outer set, while theunit 19 'of the innerset is of a diameter slightly. less than the unit 17 and greater than the unit 18 and occupies a position above --thetwo units 17 and 18y and in substantially the horizontal plane of the outer unit 11.v The three units comprising the inner set are providedat opposite sides with intercommunieating passages 2O and 21, which passages occupy substantially the relative position of the sides of a triangle, the three units which they connect being likewise triangularly disposed as viewed in cross section. The inner set of heating units is provided with a steam supply 22 which is common to the three units and which Vis equipped with a control valve 23. Each set of pipes is provided with f a drain-cock 24.

When either the valve 16 or 23 .is'open heating fluid is supplied invsubstantially' uniform quantity to the outer or Vinner set of heating units as the case may be, the `Huid flowing by means of Athe endless construction of heating pipes to all ,parts of the same which are heated to .a substantially uniform degree. By the proper manipulation of the valves and supplyingthe heatinguidin greater or less quantity to the different sets of heatingunits according to the circumstances the mass of material within the kettle can be uniformly and quickly brought to and maintained at the .proper temperature to secure the best results..

I claim: y

1. In heating pparatus. a plurality of endless single coil 'pipes horizontally arranged in nested relation, and provided at intervals with` substantially unobstructed intercommuni ating passages, and a supply pipe common to more than one of said pipes, at least oneA of said intercommunicating passages beingr independent lof the passage incident to said common supply pipe.

2. In heatingapparatus, a pluralityof endless single cil pipes horizontally arranged in nested relation and provided 4at intervals with intercommunicating passages of a diameter lsubstantially equal to the inulterior diameter of said pipes, and a'supply pipe common to more than one of said pipes, at least one of said intercommunieating passages being independent off the passage invmon te said pipes rnd discharging at a point substantially midway between said pipes.

5. In heating apparatus, a plurality of intercommunicating, endless, single coil pipes in substantially concentric relation and another endless single coil pipein a difl'erent planefrom the plane of said first named pipes `and in communication with all of said first mentioned pipes.

6. In heating apparatus, the combination of a set of two intercommunicating pipes horizontally arranged in superposed relation and provided with a supply pipe common to both, and a second set of three intercommunicating pipes horizontally arranged in nested relation within `the first set and triangularl'y disposed as viewed in cross section, the three provided with 'a common *I supply pipe, substantially as described.

7. In heating apparatus, the combination with a receptacle, of a plurality of'endless single coil pipes horizontally arranged in nested relation and provided at intervals with substantially unobstructed intercom- Amunicating passages, and a` supply pipe common to more than one of said pipes, at least one of said intereommunicating passages .beinnr independent of the passage incident to said common supply pipe.

means to supply a heating medium to the,

members of each set in common and to the two sets independently, substantially as described. p

9. In heating apparatus, the combination with a receptacle, of a set of two intercommunicating annular pipes horizontally' ar' ranged therein in sup'erposed vertical relation, a. second set of three intercommunicating pipes horizontally arranged within the firstC set in superposed triangular relation, a supply pipe `common to the members of the outer set, and a second supply pipe common to the members of the inner set, substantially as described.

10. In heating apparatus, the combination with a receptacle, of a set of two intercommunieating single-coil pipes horizontally arranged in superposed relation and provided with a supply pipe common to both, and a second set of three intercommunicating single-coil pipes horizontally arranged in nested relation within the first set and triangularly disposed as viewed in cross section, lthe three provided with a common supply. pipe substantially as described.

11. In heating apparatus, a set of three intercommunicating single-coil pipes horizontally arranged in nested relation and triangular-ly disposed as viewed in cross seetion, the diameter of the' coil formingV the apex of the triangle being less than that of one of the others and greater than that.of the third.

In witness whereof I have hereunto signed my name in the presence of two witnesses.
